New perfluoropropylated and perfluoro-oxaalkylated 4-vinyl-pyridinium chloride oligomers with carbon-carbon bond formation were prepared by the reactions of the corresponding fluoroalkanoyl peroxides with 4-vinylpyridinium chloride in excellent to moderate yields under very mild conditions, These fluorinated oligomers were effective for reducing the surface tension of water to around 10 mN m(-1) with a break point resembling a CMC (critical micelle concentration), and are applicable to new fluorinated cationic oligosurfactants.
